RESCUE reads BAD floppy disks! If you have a disk that returns GENERAL FAILURE READING DRIVE (X). RESCUE will read it anyway. RESCUE will even read a disk that you poke a hole in. Of course you cannot read the DATA in the bad area but you can recover the rest. You will mark the areas you want to recover and then save those marked areas in files you name or have RESCUE try to locate all the DATA that belongs to a file for you. You will instruct RESCUE what to name these files and where to put them on another floppy or your hard drive. You may also instruct RESCUE to simply print out your marked areas. RESCUE , Data Recovery Reference Section 5 INTRODUCTION RESCUE is a RAM-based disk reader that offers a wealth of features designed to make the program powerful yet extremely easy to learn and use. RESCUE offers users a choice of using a sliding menu or quick F key hit for all of the major program functions. RESCUE has a very short learning curve. RESCUE's logical, easy to use, easy to learn structure is the result of setting up a software package in a logical use sequence. You will be utilizing and running with RESCUE in no time. If you are new to data recovery you will be surprised at how easy RESCUE is to use and how quickly you'll be able to learn all the advanced features of RESCUE . Note: Some disk failures may be beyond RESCUE's ability to recover data. RESCUE , Data Recovery Reference Section 6 GETTING STARTED RESCUE requires an IBM PC or close compatible with 256K, two disk drives or hard drive a color/graphics or monochrome card and monitor (VGA, EGA, CGA or MONO), and a printer. Before you start using RESCUE, you should be familiar with your computer's operating system (DOS), how to make a copy of a diskette, and how to load and run a program. RESCUE was designed to be useable on Color or Monochrome monitors. The RESCUE Program Disk Your RESCUE program disk includes the following files: - RESCUE.EXE The main program file. - DRS.DOC This File - INSTALL.EXE Install program, sets color, printer port, etc. You should make a backup copy of your RESCUE program disk, and store the original in a safe place. Never use your original RESCUE program disk as your working copy. There are two common ways to use RESCUE. Keep a copy on your hard drive for recovering floppy disks and keep a copy on a floppy for use on the hard drive. RESCUE , Data Recovery Reference Section 7 SETTING UP RESCUE Floppy Disk System: 1. With your computer turned off, open the door to Drive A, and insert your DOS disk. 2. Close the door to Drive A and turn on your computer. (Be sure to have a blank formatted disk to make your working copy of RESCUE on.) 3. If DOS asks you for the date, enter the date in the following format: mm-dd-yy, or mm/dd/yy, and then press ENTER. 4. If DOS asks you for the time, enter the time in the following format: 8:30 or 20:30, and then press ENTER. 5. When A> appears on the screen, remove the DOS disk from Drive A and insert your working copy of the RESCUE Program Disk, and close the disk drive door. Type "INSTALL". 6. When the INSTALL program runs you will be reading from drive A: and installing to drive B: Hard Disk System: 1. Turn on your computer with the floppy disk drive empty. 2. If DOS asks you for the date, enter the date in the following format: mm-dd-yy, or mm/dd/yy, and then press Enter. 3. If DOS asks you for the time, enter the time in the following format: 8:30 or 20:30, and then press ENTER. 4. When C> appears on the screen, insert your working copy of the RESCUE program disk in Drive A and close the disk drive door. 5. Type "INSTALL". 6. After you install RESCUE change to the RESCUE sub-directory by typing CD\RESCUE. 7. Type "RESCUE" to start the program. RESCUE , Data Recovery Reference Section 8 STARTING RESCUE Floppy Disk System: 1. Insert your DOS System disk in drive A:, and turn on your computer. After your system starts remove the DOS disk. 2. Insert the copy of the installed RESCUE program disk in Drive A. Type RESCUE and then press Enter. Hard Disk System: 1. After starting your computer, type CD and then type the name of the directory you copied your RESCUE files to with INSTALL. For example, if the directory is called Text, you would type CD\TEXT. Then press Enter. 2. Type RESCUE and then press Enter. 3. On a Hard Disk System, you can use the DOS Path command to start RESCUE from any DOS prompt. For more information on the DOS Path command, consult your DOS manual. The RESCUE opening screen will appear after the program is loaded. Please read the opening screen. The opening screen will provide information concerning how to contact the publisher, etc. Now, simply press any key to continue. The next screen you see will be the main sliding menu. This is the primary menu and main selection area. You will always return to this area when moving from one function to another. As you glance over this main menu two features will catch your attention. First, there is the main sliding menu select on the left side of the screen. Second, there is an information box in the lower left side of the screen. RESCUE , Data Recovery Reference Section 9 The information box in the lower left will not contain information until something is done in the program. This box will remind you of what is currently selected as well as indicating if the MARK setting is in effect. ------------------------------------------------------------------- NOTE => The MARK feature refers to a block of data you have marked to save or print. ------------------------------------------------------------------- The outlined box on the lower right never changes and simply informs you how to slide up and down the main selection menu as well as make selections. RESCUE , Data Recovery Reference Section 10 QUICK START (for experienced computer users) Start RESCUE Once you are at the main menu, select INITIALIZE floppy. Next select BROWSE/SAVE/PRINT. From the VIEW screen you can MARK then SAVE or PRINT the information your looking for on the bad disk. RESCUE , Data Recovery Reference Section 11 ------------------------------------------------------------------- TIP => If you only need a single screen of data from your bad disk it can be advantageous to just hit the PRINT SCREEN key on your keyboard to get a copy of the screen rather than bother to MARK and SAVE or PRINT. ------------------------------------------------------------------- RESCUE does not force you to memorize anything. Everything is displayed right in front of you and is readily useable. RESCUE , Data Recovery Reference Section 12 FLOPPY DRIVE HELP (F1) To select the FLOPPY DRIVE HELP screen, from the main menu, use the UP or DOWN arrow key to highlight FLOPPY DRIVE HELP. Next select the highlighted choice by hitting ENTER. As you become more familiar with the menu options it will become easier to just hit the appropriate F or FUNCTION key. The function key for FLOPPY HELP is F1. After selecting FLOPPY HELP you will be presented with the first of four screens with information pertaining to the operation of floppy recovery. To exit the first screen hit Q to QUIT or hit any other key to call up the next FLOPPY HELP screen. The procedure is the same for each successive screen. Floppy Help Screen 1 The first help screen explains that before you can attempt to recover a bad floppy disk you must initialize the RESCUE software. RESCUE requires this function to correctly read a bad floppy disk. Floppy Help Screen 2 Screen 2 goes on to explain how initializing is accomplished by inserting a good formatted floppy disk of the type and size of the bad disk you want to read. Next RESCUE reads and establishes the parameters for the drive to be used (more on this under F2). Floppy Help Screen 3 Help Screen 3 explains some of the unusual things that can occur during RESCUE operation. RESCUE will always try to read a drive even if there is nothing in it. It will do it just fine and return what it finds, ZEROs! When RESCUE reads beyond the end of a disk it does not return an error message but keeps displaying the same last sector. Floppy Help Screen 4 Screen 4 now explains that, after initializing the drive to remove the good, formatted floppy and replace it with the bad disk. After selecting F3 or highlighting the BROWSE option you are now ready to browse through the bad disk marking, saving, viewing or printing the areas you are interested in. NOTE: You may hit Q or ESC for QUIT on any help screen and return to the main menu at any time. RESCUE , Data Recovery Reference Section 13 FLOPPY DRIVE INITIALIZE (F2) The first window that pops up instructs you to insert a good formatted disk. This is not the help area that tells you what is going to happen but actually the time to insert the good disk. The second window wants to know which drive you are using? The one you just put the disk in! Enter A, B, C or D. It makes no difference if the letters are upper or lower case. After you hit a letter key this window will be replaced by window number three which will display the status of the drive being read. After the initialize segment is complete you should remove the floppy disk and insert the damaged disk. You are ready to proceed to the BROWSE, SAVE, PRINT section. RESCUE , Data Recovery Reference Section 14 BROWSE/SAVE/PRINT (F3) After selecting F3 or highlighting the F3 choice you will be presented with the BROWSE/SAVE/PRINT screen. This is the main screen of the RESCUE software. From here you are presented with a view screen and 12 selection keys as shown below. +--------+ +--------+ +-----------+ +--------+ +---------+ +--------+ ª (A)uto ª ª (B)EEP ª ª (D)ISPLAY ª ª (F)IND ª ª (P)RINT ª ª (S)AVE ª +--------+ +--------+ +-----------+ +--------+ +---------+ +--------+ +--------+ +--------+ +-----------+ +--------+ +---------+ +--------+ ª ()UP ª ª ()DWN ª ª (J)UMP ª ª (M)ARK ª ª (H)ELP ª ª (Q)UIT ª +--------+ +--------+ +-----------+ +--------+ +---------+ +--------+ The letter enclosed in each bracket is the key to be depressed to activate that function. Example: If you wanted to QUIT you would hit the Q key which would highlight the (Q)UIT box momentarily as well as beep followed by a return to the previous level. The upper right box on the screen will display the current sector that is being viewed. The area between the current sector display and the boxed keys is the text or hex display area. This area will display the current selected sector. RESCUE , Data Recovery Reference Section 15 BROWSE/SAVE/PRINT (F3) - THE (A)UTO KEY The A or AUTO key causes RESCUE to BROWSE your disk by incrementing the sector count by plus one and then displaying the sector. The process continues to repeat itself until you press any key. The BROWSE begins at whatever sector you were at when you first selected AUTO. EXAMPLE: You might want to begin a BROWSE at sector 100 and you are currently at sector 675. You might hit J to jump to sector 100 then A for AUTO to watch RESCUE page through the disk sector by sector. The AUTO browse mode will bring up several new features. You will be presented with a speed control feature. This is handled by the () and () keys. The up arrow makes the display move faster and the down arrow slows the display down. There is a display index number provided on the right hand edge of this line. While you are in AUTO mode the words, "SPACE BAR = STOP" will appear at the bottom center of the screen, directly above the key box display. When you touch any key the AUTO mode stops and then redisplays the last sector you were viewing. You can now easily arrow UP or DOWN to find the exact sector you are looking for. RESCUE , Data Recovery Reference Section 16 BROWSE/SAVE/PRINT (F3) - THE (B)EEP KEY The B or (B)EEP key is the simplest key on the menu. When you press it the first time it shuts off the BEEP sound heard with each key hit. If you press it a second time then it turns the sound back on. When you hit the (B)EEP key a message is automatically displayed showing the current status of the beep sound. This message will erase itself from the screen after 3-seconds. RESCUE , Data Recovery Reference Section 17 BROWSE/SAVE/PRINT (F3) - THE (D)ISPLAY KEY The (D)ISPLAY key switches between ASCII (Normal Characters) and HEX displays. When you hit the D key you are toggled to the opposite display that is currently being displayed. After D is pressed the BROWSE display will refresh showing the current sector in the new format, ASCII or HEX. RESCUE , Data Recovery Reference Section 18 BROWSE/SAVE/PRINT (F3) - THE (F)IND KEY The (F)IND feature is designed to locate text for you. After you hit the F key you will be asked where to begin the search. You should enter the sector number where the search is to begin. Next you will be prompted for the search text. Enter up to ten characters that RESCUE is to search for. RESCUE is case sensitive at this point so be sure to only use capitals where they belong. RESCUE will now begin to search for the text specified and at the location specified. The search will progress one sector each step until the data is found. FIND is the slowest running operation in RESCUE , therefor you should position the FIND start as close to the area to be searched. This assumes that you know where you would like to begin. If the start area is unknown the FIND will have to start at sector zero (0). After RESCUE finds the text being searched for it will stop the search and display the found text sector. RESCUE , Data Recovery Reference Section 19 BROWSE/SAVE/PRINT (F3) - THE (P)RINT KEY To utilize the print function you must first have something MARKED. See (M)ARK instructions. When you hit P for PRINT RESCUE will begin to print out each sector starting with the lowest marked sector and proceeding up to and including the largest marked sector. You will be asked if you want to print ALL characters or just non-control characters. If you select ALL sometimes your printer will do unpredictable things based on the control characters, carriage returns and line feeds it finds in the data stream. If you select straight ASCII the control characters will be suppressed and your remaining ASCII data will be printed. RESCUE , Data Recovery Reference Section 20 BROWSE/SAVE/PRINT (F3) - THE (S)AVE KEY The (S)AVE key saves data between MARK sets into a file that you name. (See MARK command for details on MARK.) When you are prompted for a file name you may use any valid DOS name. This means up to 8 valid characters followed by a period and then 3 more valid characters. INVALID Characters are: . " / \ [ ] : | < > + = ; , and all characters below ASCII 33. Included with the file name may be a path. If you do not want the data saved into a file on the current logged path just add the drive and path name to the front of the file. EXAMPLE: To save MYDATA.TXT to drive C and in the subdirectory \TEMP you would type C:\TEMP\MYDATA.TXT If you pick a name that already exists RESCUE will inform you that the name selected already exists and then prompt you for a new name. Once the name you used is correct then each sector between the data you marked is saved into your named file. After the data has been saved, RESCUE will inform you that ALL MARKS have been cleared and you are ready for the next function. RESCUE , Data Recovery Reference Section 21 BROWSE/SAVE/PRINT (F3) - THE ()UP KEY The () arrow key causes RESCUE to increment one sector and then display that sector. This is the key to use for browsing or moving short distances in the browse area. As you hit the up arrow key not only will the display change but the sector counter will also incre- ment by one in the upper right corner of your screen. If you are on the very last sector of the disk the display will not change. The sector display will change but the data in the view window will not. RESCUE , Data Recovery Reference Section 22 BROWSE/SAVE/PRINT (F3) - THE ()DOWN KEY The () arrow key causes RESCUE to decrement one sector and then dis- play that sector. This is the key to use for browsing or moving short distances in the browse area. As you hit the down arrow key not only will the display change but the sector counter will also decrement by one in the upper right corner of your screen. If you are on the very first sector of the disk the display will not change. It will remain on the zero sector along with the sector counter. RESCUE , Data Recovery Reference Section 23 BROWSE/SAVE/PRINT (F3) - THE (J)UMP KEY The (J)UMP key is used to move large numbers of sectors. If you are on sector 10 and wanted to move to 1500 it would be prohibitive to use the up arrow key. It is simpler to JUMP to 1500. When you select JUMP you will be prompted for the sector number via a small window. After the JUMP is complete the sector JUMPED to is displayed. RESCUE , Data Recovery Reference Section 24 BROWSE/SAVE/PRINT (F3) - THE (M)ARK KEY The (M)ARK key is used to select an area from your disk. You use the MARK key to specify the beginning and the end of an area you wish to save. Hit the MARK key when you are in the sector you want to begin in. A pop-up window will tell you that the first MARK has been set. You will then be presented with the choice of either MARKing the end sector manually, or using the (T)RACE feature. If you select MARK, your next step is to arrow up to the ending sector Once this is done, you then hit the MARK key again and you are then ready to (S)AVE or (P)RINT the area now marked off. Note: Each of the pop-up windows that are displayed when you MARK a sector will clear themselves from the screen within a few seconds.If you hit the MARK key a third time it will clear, or erase, all previous MARKS. If you select TRACE (intended primarily for text or ASCII files), RESCUE will attempt to automatically trace through the disk locating the sectors that belong to the file that you are trying to recover. The file may be 'fragmented', or spread out into many pieces throughout the disk. By using the TRACE feature, RESCUE will attempt to read the File Allocation Fat (FAT) for you. By locating the section that contained the cluster number of the beginning sector you marked, RESCUE can determine what other clusters/sectors belong to that file. As TRACE finds each sector, it is displayed on the screen. You will find that the sectors are not simply in order, so you must (S)AVE or (P)RINT the TRACED information immediately. If you accidently lose the TRACED information, for example by hitting the MARK key, just hit the MARK key once more to drop all information and start over. IMPORTANT NOTE: There are numerous ways for the TRACE feature to make mistakes or fail. One way is that while working its way back- wards from your marked sector it may pass through an END-OF-FILE marker and lose track of where it is. END-OF-FILE markers in the middle of a sector tend to mess things up as well. Another way is that the sector you MARKed may only be a piece of a file that was once deleted. THE USER MUST BE AWARE THAT THERE MAY BE FILES BEYOND TRACE's ABILITY TO RECONSTRUCT (particularly executable files - .EXE, .COM, .BAT, etc, as well as binary and even some text files.) If the TRACE feature dead-ends before finding all of your data, there is a good chance that you had the same file on the disk that was once deleted and you are looking at a portion of the deleted file. If so, find the same file from a different sector and try again. RESCUE , Data Recovery Reference Section 25 BROWSE/SAVE/PRINT (F3) - THE (H)ELP KEY The (H)ELP key provides brief information on using MARK, SAVE and PRINT. If you hit the help while on the view screen a window pops onto the screen with information concerning MARK. Hitting any other key at this time will present the next screen with SAVE information and so on. There are a total of four help screens in this area. You may quit viewing HELP screens at any point by simply hitting Q for QUIT. RESCUE , Data Recovery Reference Section 26 BROWSE/SAVE/PRINT (F3) - THE (Q)UIT KEY The (Q)UIT key is simply what it says. When you hit the Q key you will leave the BROWSE/SAVE/PRINT area and be returned to the main sliding menu area. All marks you set as well as the current logged drive and the current active sector are still in effect. This way you will be able to return to the same place you were at. RESCUE , Data Recovery Reference Section 27 FLOPPY INFORMATION(F4) The floppy drive information selection presents you with valuable information concerning disk sizes, types. The information as to size, format and capacity are given for each floppy type; 1.44M, 1.2M, 720K, 360K. RESCUE , Data Recovery Reference Section 28 DOCUMENTATION (F5) RESCUE has two forms of documentation. One is the printed manual and the other is the same manual under the F5 function. If you are using the book under the main sliding menu F5 function then simply PgUp or PgDn to the area you are looking for. You may also use the up and down arrows to move one line at a time. "Q" for QUIT at any time will return the user to the main sliding menu. RESCUE , Data Recovery Reference Section 29 EXIT PROGRAM (F6 or ESC) F6 or ESC simply terminates the RESCUE program refreshes and clears the computer screen leaving you at the default DOS prompt.
